As hectic of a day as it was, national signing day was a success for all Big 12 programs. Coaches were up early manning their fax machines and showing excitement with every national letter of intent submitted via fax.

Nearly 250 football players signed letters of intent to play Big 12 football on Wednesday. Here are five of the biggest storylines -- and a bonus storyline that could have an ending Thursday -- from the conference.

Oklahoma takes over top spot in Big 12

In the past 48 hours, everything seemed to go Oklahoma’s way.

All four players were a part of Oklahoma’s signing class of 26 on Wednesday -- helping the Sooners take over the top spot in the Big 12 class rankings. Oklahoma’s class is No. 13 nationally, three spots better than previous top dog Texas.

Oklahoma in previous years has been very good at finishing strong in recruiting. It managed to sign Frison, who committed to Utah last February before decommitting last month, as well as Brown, who had been committed to Tennessee since May before making an 11th-hour change.

Strong, Longhorns get their DTs

New Texas coach Charlie Strong wanted two players he recruited to play at Louisville, and by Wednesday afternoon, he had them.

While Rhoads is pumped about the entire class, there’s something special about Lazard, as he is this year’s only in-state signee. Lazard, No. 148 in the ESPN 300, had opportunities to sign with other programs, but he chose to honor his original commitment and also follow the footsteps of his father Kevin Lazard, who played in the secondary for the Cyclones in the early 1990s.

“This is a young man who has gotten phenomenal national attention and was recruited by the traditional historical programs in college football and kept on turning them away to stay true to his word to be an Iowa State Cyclone,” Rhoads said in a statement of Lazard, the No. 2 prospect out of the state of Iowa behind Alabama offensive lineman signee Ross Pierschbacher (Cedar Falls, Iowa/Cedar Falls).

West Virginia adds depth in class

Adding depth was the objective for West Virginia coach Dana Holgorsen, as he signed 22 players on Wednesday. Holgorsen was fortunate to add depth from coast to coast.

Of the 22 commits, only one -- three-star offensive tackle Amanii Brown (Morgantown, W.Va./Morgantown) -- is an in-state signee. The Mountaineers hit points all over the Lower 48, from California to Texas to Florida, to get players who can be contributors early and help the program return to star status.

West Virginia’s class is led by five ESPN 300 players. Running back Donte Thomas-Williams (Durham, N.C./Hillside), the class’ top-ranked player, was the last to commit early Wednesday afternoon. He joins defensive back Dravon Henry (Aliquippa, Pa./Aliquippa), linebacker Davonte James (Springfield, Ohio/Springfield) and receivers Lamar Parker (Miami/Booker T. Washington) and Jake McCrary (Miami/Coral Reef) in the class.

Bonus: Could the Sooners add one more?

LSU signed 22 players on Wednesday. The Tigers were hoping to sign 23.

Deondre Clark (Oklahoma City/Douglass) has been verbally committed to LSU since July, but the ESPN 300 defensive end also has high interest in Oklahoma. There were conflicting reports on Wednesday regarding whether Clark actually signed and submitted his letter of intent to LSU.

ESPN’s David Ching said an LSU spokesperson confirmed the letter of intent was at LSU and cleared compliance. Outside reports, however, say Clark did not submit the letter of intent, and a tweet from Clark's Twitter account said that “nothing is final.” His mother Dorshell also told The Oklahoman that her son “has not signed with LSU.”

Oklahoma City schools were closed on Wednesday because of bad weather, so Clark didn’t fax anything by way of Douglass High School. He is expected to announce his final decision on Thursday.

If it's true that Clark has not signed with LSU, look for Oklahoma to be a key player in his final decision. Ranked No. 273 in the ESPN 300, Clark has built a great relationship with the Sooners' coaching staff, particularly defensive line coach Jerry Montgomery.
